SUGAR LAND, Tex., Oct. 30 -- President Bush said terrorists will win if Democrats win and impose their policies on Iraq, as he and Vice President Cheney escalated their rhetoric Monday in an effort to turn out Republican voters in next week's midterm elections.

Democratic operatives continued to broaden the field of races they believe are competitive enough to merit last-minute investments, as the party's House election committee launched ads in typically conservative districts of Kentucky, Nebraska and Nevada. In the Senate battle, new public and private polls yesterday indicated very tight races in Tennessee, Virginia and Missouri, the last of which is shaping up as possibly the country's tightest contest.

President Bush returns a crying toddler to his parents at a campaign rally at Georgia Southern University. Bush said Democrats retaking control of Congress would be a victory for terrorists.

Faced with potential GOP defeat in both chambers, Bush and Cheney aimed to avert that by convincing voters that they cannot risk giving the opposition party any power in Washington.

"However they put it, the Democrat approach in Iraq comes down to this: The terrorists win and America loses," Bush told a raucous crowd of about 5,000 GOP partisans packed in an arena at Georgia Southern University in Statesboro, one of his stops Monday. "That's what's at stake in this election. The Democrat goal is to get out of Iraq. The Republican goal is to win in Iraq."

Democrats reacted sharply to the latest White House attacks. Senate Minority Leader Harry M. Reid (Nev.) said Bush "resorted to the same tired old partisan attacks in a desperate attempt to hold on to power." House Minority Leader Nancy Pelosi (Calif.) said Bush is looking to retain a "rubber-stamp Republican Congress that has done nothing to change our failed Iraq policy."

Cheney, meanwhile, said in an interview with Fox News that he thinks insurgents in Iraq are timing their attacks to influence the U.S. elections.

"It's my belief that they're very sensitive of the fact that we've got an election scheduled," he said. Cheney said the insurgents believe "they can break the will of the American people," and "that's what they're trying to do."

George Bush has confused the opponents of the GOP with the enemies of the United States.
